【摘要】：目的:使用顯微CT掃描技術(shù)研究中國人離體下頜切牙根管系統(tǒng)解剖形態(tài)。方法:收集108顆中國人下頜切牙,使用顯微CT進(jìn)行掃描后構(gòu)建根管系統(tǒng)三維可視化模型。對(duì)主根管形態(tài)進(jìn)行分型,記錄第二根管分出位置,分支根管的發(fā)生率和位置。結(jié)果:下頜切牙根管最常見的形態(tài)為VertucciⅠ型和Ⅲ型,發(fā)生率分別為78.70%和14.81%,分支根管發(fā)生率為24.07%。第二根管發(fā)出位置在釉質(zhì)牙骨質(zhì)界根方(6.07±3.42)mm。結(jié)論:下頜切牙根管系統(tǒng)解剖形態(tài)復(fù)雜,了解其主根管及分支根管的發(fā)生規(guī)律對(duì)于提高根管治療成功率具有重要意義。
[Abstract]:Objective: to study the anatomic morphology of the root canal system of Chinese mandibular incisor by microscopic CT scanning. Methods: 108 mandibular incisors of Chinese were collected and scanned with microscopic CT to construct a 3D visualization model of root canal system. The morphology of the main root canal was classified to record the location of the second root canal and the incidence and location of the branch root canal. Results: the most common forms of root canal of mandibular incisors were Vertucci type 鈪，
